A single MCP endpoint exposes our entire API as ~170 tools your agent can call. Bring your own API key — works with Claude, Cursor, ChatGPT, GitHub Copilot, Gemini, and a dozen other clients.
Anthropic's official CLI for Claude. Native support for remote streamable-http servers and per-request headers.
claude mcp add --transport http apininjas https://mcp.api-ninjas.com/mcp/ \
--header "X-Api-Key: YOUR_API_NINJAS_KEY"{
"mcpServers": {
"apininjas": {
"type": "http",
"url": "https://mcp.api-ninjas.com/mcp/",
"headers": { "X-Api-Key": "YOUR_API_NINJAS_KEY" }
}
}
}Your key is on the Free or Learner plan. The MCP server requires the Developer plan ($59/month) or higher. Upgrade your plan to connect.
Your X-Api-Key header isn't reaching the server, or the key isn't valid. Confirm the value matches the key on your profile page. Header names are case-insensitive — that part is fine.
A successful connection lists roughly 170 tools (one per API Ninjas endpoint). Some clients filter or paginate — check your client's tool browser settings.
Wrap our endpoint with the mcp-remote bridge to convert it into a stdio process: npx -y mcp-remote https://mcp.api-ninjas.com/mcp/ --header "X-Api-Key:YOUR_API_NINJAS_KEY"
Each tool call counts against your normal API Ninjas quota. Upgrade your plan for higher rate limits, more requests per month, and access to premium-only fields. Still stuck? Contact us.
